TIRE-PROTECTOR.

Specification of Letters Patent. Patented Jillie 13, 1911;

Application filed November 30, 1910. Serial No. 594,856.

To all whom it may concern:

Be it known that 1, JAMES F. CoLLi'Ns, a

in the county of Allegheny "and State of Pennsylvania, have invented certain new and useful Improvements in Tire-Protectora'of which the following is a specification.

The prime object of my invention is to provide, new and improved means for protecting pneumatic tires of automobile and other vehicle wheels. 7

A further object of the present invention. is to provide a tire protector for tires of the class mentioned that will not aitect the resiliency of the tire, and at the same time provide a simple and efficient means for protecting the tire.

In the accompanying drawings, which illustrate applications of my invention, Figure 1 is a side elevational view of a portion of an automobile wheel embodying my in vontion; Fig. 2, an enlarged. vertical sectional view the section being taken on line IIII of ig. 1,; Figs. 3, 1 and 5 detail views of the wheel-rim, Fig. 3 being'a plan showing the rim rolled into operative position, Fig. 4 a sectional View, and Fig. 5 a planof the blank from which the rim is formed; Fig. (3, a plan view of an interlocking securing member or strap; Fig. 7 a side elevational view. of same; Fig. 8, a plan view of a supplementary securing member or strap; Fig- 9, a perspective view of a section of a tread-member: Fig. 10, a cross-sectional view particularly showing anti-skidding Fig. 11, an enlarged sectional view showing a modified form of my invention; Fig. 12, a part sectional View and apart elevational view showing an application of the form of Fig. 11; and Fig. 13, a plan of a still further modified form of tread-member showing the securing means made integral therewith.

Referring to the drawings and first to the form of Fig. 1. 1 designates thewheel, and 2 the rim thereof. The outer tube 3 of the pneumatic tire of well knownconstruction is mounted on the rim 2 and secured thereto. in the usual manner.

1 designates the inner matic .tire;

As illustrated and as preferred, the rim is provided with two series of edge notches tube of the pneu- 'rim' of the wheel. vendtwospaced tongues 10.each having a gave the rolled unnotched portion 5, and with two series of slots or openings 6. It will benoted that the notches 5. of each series, when the ram is bent into operative position as shown by Fig. 3, will assume positions over the openings (l of the respective series ofopenings formed in the rim. I

Circumferentially disposed on the outer tube 3 is a sectional member or a plurality of members 7. These. members 7 are preferably madeof thin sheet metal, and in the construction illustrated, I have shown six members of the form of an inverted U in cross-section with c.1611 innei edges rounded, as shown at a, and each formed with openings 8 adapted to receive anti-skiddingmemhers 9. In this form ofmy lnvention the members 7 constitute portions of the tread of the wheel or the tread of The members constituting the treads'portions may be varied'from the number shown,

but a sufiicient number should be employed the r in order not to affect the resiliency of tire, and the adjacent meeting ends'of said members are preferably spaced apart as constituting shown. The series of members the tread-member are securely -connectd with the rim of the wheel by-suitable detachable securing means and, as illustrated, these means comprise members 10 and 11, respectively designed to encircle the tire and treadmember and engage or interlock with the rim. Securing members 10 are disposed at.

the ends of the several-members 7, and members 11 are located between and alternate with memberslO. Members 10 are'preferably formed ofleather although they may be formed of other suitable material and are each provided with means for engaging the As shown, I form at each portion 12 designed the rim,

} to enter a notch 5 of and each having shoulders 13 to enof the rim. The outer ends of the tongues project through the openings 6 of the rim. This construction provides a siinple'and eflicientinterlocking means for locking the securing members to the rim. Members .10 are also provided with holes 14 through-which the members 9 of the treadanember project- The members 11 are designed to be locked to the rim of the wheel in substantially the same manner as members 10, member-s11 however have only a single tongue 15 at each end, but are provided with openings 16 to receive members 9 and with a portion12 and shoulders 13 portion 12 and the shoulders 13 of the memthe protector.

corresponding with. the

' in order to receive said members 9 members ,20

- readily bers 10. The

protector is applied to the tire before the latter is inflated, and it will be erly assembled with the locking'mernbers l0 and 11 in coacting relation with rim, an inflation ofthe tire will cause the protector to be firmly held 'in. position on the tire.

In the modified form of my invention illustrated by Figs. 1].. and"l2,cthe wheelrim and the tire are the same as in the form of Fig. 1. In this latter construction how-.

ever, I show fewer members 7", corresponding with the members 7, than in the form of Fig. 1, and these members 7 a members or pieces-20 which latter constitute the tread-members of the protector. In this form of my invention the'members 7 are provided with projecting members 9 and member 23 of'the protector -is made of leatherand designed to'cover the steel plates as in the form of Fig. 11, but the securing means 24 are made integral with said membars 23.

'What I claim is 1. The combination with a wheel rim ha. ing an, iiiturned upper edge formed with a notch,'of a tire mountedo n the rim, a tire protector comprising a plurality oi circumferentially disposed spaced members, antiskidding projections on said members, and

means for securing the spaced members to seen that when the parts are propterenti'ally are covered by sk dding-pro ections on said members, and

the wheelrim comprising a'band having an opening therein to receive an anti-skidding projection and a tongue formed on one end thereof, said tongue entered in the notch of the inturnededge-and engaging the edge adjacent to thenotch.

- 2. The combination with a wheel rim having intur'ned upper edges each having a series of notches formed therein and said rim provided with a series of'openings disposed below the notches and'in line therewith, of a pneumatic tire mountedon the rim, atire protector comprising a plurality of circumdisposed spaced members, antimeans for securing the spaced niembers'to the wheel rim comprising aband formed with openings to receive the anti-s'lriddin'g pro ections and havinga tongue formed on 'each end thereof, said tongues entered in the notches of the inturned' port-ions and-en gaging the same adjacent to the notches and projecting through the registering openings of the wheel IlIII. 3. The-combination with a wheel rimhaving inturned edges each provided with'aseries of notches, said wheel rim having a series of openings registering with said notches, a tire mounted on the rim, a plurality of spaced members circumferentially disposed on the tire, each provided with an antiskidding projection, and a series of tread-members mounted, on the first'mentioned members, a

securing band extending through each of the latter members and having a tongue at each end thereof, said tongues entered in thenotches and extending through the openings ofthe rim.

' In testimony whereof I afiix my signature in presence of two witnesses.
